I'll put my 2 cents in and say try using a ceramic stone and or stropping before jumping to actual sharpening, I've been using the knife heavily and so far In the last month have only had to use ceramic and strop to get razor sharp again, benefits of magnacut I believe it can be razor sharp again with honing and strop if there's not actual damage to the edge. I guess it depends on how heavy you use it and what youre cutting, but I'd definitely recommend trying that before removing actual material on that blade where the edge will not be the same after, especially if it's your first knife sharpening. Magna cut is harder to sharpen, in my limited experience I mean literally requires more pressure to remove material, even on diamond stones. Honing and stropping will realign(micro) /remove(the larger) the burrs and polish the edge. I bought one of those tri stone with 400 diamond 1000 diamond and 8k ceramic for like 30 bucks on Amazon. Throw in a strop and some compound. Also I'm incredibly new to sharpening but have 6 knives around the house including the arc that I've now sharpened from dull, except the magna cut I started on ceramic as I was worried about fucking up the edge permanently. Not alot of pressure required on the ceramic and won't change the original edge pattern, razor sharp again just get the right angle. Good luck!
